Los Angeles ? The circus that swirled around Michael Jackson when he was alive rolled on Friday as the doctor expecting to be accused of involuntary manslaughter in his death planned to stage a surrender at a courthouse but called it off after prosecutors announced charges will be filed next week.

Dr. Conrad Murray, working as Jackson’s personal physician during the singer’s preparation for comeback concerts, has been under investigation since the 50-year-old pop star died June 25 after being administered the hospital-strength anesthetic propofol and sedatives at his rented mansion to help him sleep.
